Cold Stress Is the Driving Factor of Intense Defoliation of Rubber Trees in Xishuangbanna[Jul 18, 2018]

Researchers from Xishuangbanna Tropical Botanical Garden used sap flow and climatic data of four years' (from 2013-2016) observations to explore the pattern and driving factor of intense defoliation of rubber plantations, and to determine the sensitivity of sap flow to climatic factors during the four periods.

Shadow of the Black Hole at the Center of the Milky Way in Dark Matter Halos First Calculated[Jul 17, 2018]

Observing the black hole shadow is an important method to directly detect the black hole. In a recent study published in the Journal of Cosmology and Astroparticle Physics, researchers from Yunnan Observatories of Chinese Academy of Sciences, for the first time, obtained the shadow of the black hole Sgr A* at the center of the Milky Way in dark matter halos.

Scientists Develop New Generation of Deep-ultraviolet Nonlinear Optical Materials[Jul 17, 2018]

Recently, Prof. YE Ning's group at Fujian Institute of Research on the Structure of Matter of Chinese Academy of Sciences designed and synthesized two new excellent DUV NLO crystals NH4Be2BO3F2 (ABBF) and γ-Be2BO3F (γ-BBF) based on the structure of KBe2BO3F2 (KBBF). Their excellent DUV laser output potential demonstrated a breakthrough in the field of deep ultraviolet nonlinear optical crystal.

Morphological Analysis and Molecular Evidence Delineate Two Controversial Gold‐thread Nanmu Species[Jul 17, 2018]

Researchers from Xishuangbanna Tropical Botanical Garden integrated morphology and restriction site-associated DNA sequencing to define the species boundaries of P. bournei and P. zhennan. They delineated the geographic distribution using occurrence data of herbarium specimens and their field investigation, and undertook analyses of morphological features and RAD seq data for samples of the?P. bournei and P. zhennan complex, representing their entire distributional areas.

Mixing Between Two Light Scalar Mesons Observed at BESIII[Jul 16, 2018]

Scientists observed the mixing of two light scalar mesons, a00(980) and f0(980), using data samples accumulated with the Beijing Spectrometer (BESIII). This observation should help clear up what the 980 MeV scalar mesons are made of (e.g., a tetraquark, meson molecule, quark-gluon hybrid). The results were published recently in Physical Review Letters.

Scientists Reveal Expression Networks and Inheritance Patterns in Castor Bean Seeds[Jul 16, 2018]

Prof. LIU Aizhong and his colleagues at Kunming Institute of Botany comprehensively identified and characterized 5,356 Long non-coding RNAs in castor bean seeds. Base on genome-wide analyses, they found that a small fraction of lncRNAs exhibited coordinated expression with nearby PCgenes.
